Abstract
Over the past two decades, concerns have arisen about the efficacy and safety of medicinal plants, highlighting good agricultural practices and quality control. This study aimed to validate a multi-residue analysis method for detecting 268 pesticides in Mikania glomerata tincture, using direct injection and UPLC-MS/MS, per SANTE guidelines. The validation of the method involved evaluating the linearity of analytical curves in terms of the determination coefficient r2 and residuals (%), as well as the limits of quantification (LOQ), matrix effects, precision (expressed as the coefficient of variation, CV), and accuracy (determined as the recovery percentage). The parameters and acceptance criteria were assessed based on SANTE guidelines. The method was then applied to analyse commercial samples of M. glomerata tincture, and traces of carbendazim and dimethomorph were detected. This study underscores the need for regulatory measures to enhance agricultural practices, thereby ensuring the safety and efficacy of medicinal plants.
期刊介绍:
This journal is an international medium directed towards the needs of academic, clinical, government and industrial analysis by publishing original research reports and critical reviews on pharmaceutical and biomedical analysis. It covers the interdisciplinary aspects of analysis in the pharmaceutical, biomedical and clinical sciences, including developments in analytical methodology, instrumentation, computation and interpretation. Submissions on novel applications focusing on drug purity and stability studies, pharmacokinetics, therapeutic monitoring, metabolic profiling; drug-related aspects of analytical biochemistry and forensic toxicology; quality assurance in the pharmaceutical industry are also welcome.
Studies from areas of well established and poorly selective methods, such as UV-VIS spectrophotometry (including derivative and multi-wavelength measurements), basic electroanalytical (potentiometric, polarographic and voltammetric) methods, fluorimetry, flow-injection analysis, etc. are accepted for publication in exceptional cases only, if a unique and substantial advantage over presently known systems is demonstrated. The same applies to the assay of simple drug formulations by any kind of methods and the determination of drugs in biological samples based merely on spiked samples. Drug purity/stability studies should contain information on the structure elucidation of the impurities/degradants.
